 Sun Setting Behind Mount Etna

   Summary Author:  Marcella Pace

   The photos above show  the Sun setting behind the  Mount Etna
   (10,892 ft or 3,320 m) summit crater complex in Sicily, Italy. It’s a
   composition of two shots from the same location without changing the
   frame; one of the Sun using a solar filter, one with no filter for when
   the Sun had moved out of frame. I calculated the ideal position to get
   the most dramatic shot. Note that although no  sunspots are visible
   here, the solar disk was partially obscured by smoke from  the
   volcano's multiple summit craters. When these photos were snapped, and
   during the days before, there was activity from the  Voragine Crater
   as well as blasts and discontinuous emissions of ash from the Northeast
   Crater and the New Southeast Crater. Photos taken on February 18, 2020.
